Description

This star quartz, or more adequately “asteriated quartz” is a rounded polished specimen that shows a six-rayed star, orientated in a plane perpendicular to the c-axis. According to the bibliography (i.e.: Schmetzer, 2003; Schmetzer, 2006) this asterism effect is enhanced by three groups of needle-like inclusions. Acquired in 12/4/1983 in Ratnapura by Mr. Gustaf for USD25. We have found the original invoice, that will be delivered with the specimen.

Ex Gustaf collection #110, with his handwritten label.
